preparation example Construction

[0076] The preparation method of the antibacterial finishing agent is generally to prepare respectively a certain concentration of propolis ethanol solution and a certain concentration of chitosan solution, and then measure a certain volume of propolis ethanol solution, which is added to the prepared chitosan solution, Mix and stir until smooth.

[0077] Because propolis is insoluble in water and can be dissolved in organic solvents such as ethanol, ethanol is preferred as the solvent for dissolving propolis, and ethanol is non-toxic and volatile, and will not cause residues on fabrics. In a sense, ethanol is also green and environmentally friendly product.

[0078]The above-mentioned preparation operation is simple, practical, easy to implement, high in efficiency, low in cost, does not require complicated operating equipment, and is industrialized and mass-produced.

[0079] In a preferred embodiment, the preparation method of propolis ethanol solution comprises:

[0080] ...

Embodiment 1

[0098] An antibacterial finishing agent, comprising the following components:

[0099] 15g / L propolis ethanol solution and 5g / L chitosan solution.

[0100] Wherein, the preparation method of propolis ethanol solution comprises:

[0101] 15 g of propolis was weighed, chopped, added to 1000 mL of ethanol solution with a volume concentration of 60%, extracted at room temperature for 72 hours, and impurities were removed to obtain propolis ethanol solution.

[0102] The application method of this antibacterial finishing agent comprises:

[0103] Measure the propolis ethanol solution 5mL of prepared 15g / L, join in the chitosan solution of 995mL 5g / L, fully stir, obtain antibacterial finishing dispersion liquid, this antibacterial finishing dispersion liquid is equivalent to 0.5% (volume fraction ) of propolis 60% ethanol solution. Padding pure cotton 40s / 144×96 satin fabric, adopting the method of one dipping and one padding, the padding ratio is 80%, and drying at 120°C. After...

Embodiment 2

[0105] The difference with Embodiment 1 is that in this embodiment:

[0106] Methods of application of antimicrobial finishes include:

[0107] Measure the prepared 15g / L propolis ethanol solution 1mL, join in the chitosan solution of 999mL 5g / L, fully stir, obtain antibacterial finishing dispersion liquid, this antibacterial finishing dispersion liquid is equivalent to 0.1% (volume fraction ) of propolis 60% ethanol solution. Padding pure cotton 40s / 144×96 satin fabric, adopting the method of one dipping and one padding, the padding ratio is 80%, and drying at 120°C. After padding, the remaining working solution is kept and placed to observe the stability of the working solution.

Abstract

The invention belongs to the technical field of treatment liquids for finishing textiles, and relates to an antibacterial finishing agent and a preparation method and application thereof. The antibacterial finishing agent comprises: propolis ethanol solution and chitosan solution. The preparation method of the antibacterial finishing agent comprises: adding propolis ethanol solution into chitosan solution, and fully mixing uniformly to obtain the antibacterial finishing agent. The invention uses propolis ethanol solution and chitosan solution as raw materials, not only has good antibacterial effect, high affinity to fabrics and good antibacterial durability, but also is safe, reliable, environmentally friendly, has no toxic and side effects, and has health care effects. Moreover, the preparation method is simple, practical, easy to implement, low in cost, good in environmental protection benefits, and easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of treatment liquids for textile finishing, in particular to an antibacterial finishing agent and its preparation method and application. Background technique [0002] For a long time, human health has been threatened by environmental pollution and bacterial infection; countries all over the world have paid more attention to the research on antibacterial agents, and the research on antibacterial fabric finishing solutions (finishing agents) has become a hot spot in the textile, printing and dyeing industries. [0003] At present, there are many kinds of antibacterial finishing materials used in the market, such as silver-based antibacterial materials, natural antibacterial materials, and chemical antibacterial materials. Among them, silver-based antibacterial materials mainly use nano-silver. As a new type of high-efficiency inorganic antibacterial material, nano-silver has been widely used in medicine, biol...
